Oriented multilayer film including metal layer

Abstract

The present disclosure provides a film structure. In an embodiment, the film structure comprises a machine direction oriented (MDO) multilayer film. The MDO multilayer film comprises (a) a first outer layer (FOL) comprising (i) a FOL first ethylene/a-olefin copolymer having a density from 0.900 g/cc to 0.920 g/cc, and (ii) an optional ethylene-based polymer selected from the group consisting of (1) a FOL second ethylene/a-olefin copolymer having a density from 0.920 g/cc to 0.980 g/cc; and (2) a FOL third ethylene-based polymer (LORE). The MDO multilayer film comprises (b) a first intermediate layer (FIL) in direct contact with the first outer layer. The first intermediate layer (FIL) comprises an FIL first ethylene/α-olefin copolymer having a density from 0.920 g/cc to 0.980 g/cc. The MDO film multilayer comprises (c) a core layer (CL) in direct contact with the first intermediate layer. The core layer (c) comprises a CL first ethylene-based polymer having a density from 0.920 g/cc to 0.980 g/cc; and a metal layer on the first outer layer (a).
